Sony introduces FireWire High-Speed Serial Bus IEEE 1394 LSI; facilitates connection of computers with digital AV products.SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif.--(BUSINESS WIRE)--Nov. 8, 1995--Sony Semiconductor Company of America Wednesday announced the introduction of two LSIs: a LINK-LSI "CXD CXD Coherity XML Database (Coherity) CXD Coherent X-ray Diffraction CXD Cancel Approved Departure 1940R" for digital VCR See DVR. use and a PHY-LSI, "CXD1944R," both incorporating the High-Speed Serial Bus IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 1394 LSI LSI: see integrated circuit. (Large Scale Integration) Between 3,000 and 100,000 transistors on a chip. See SSI, MSI, VLSI and ULSI. . Sample shipments will begin in April 1996. The LSIs being introduced Wednesday are based on a license from and joint development work with Apple Computer, a world leader in personal computing Refers to users working on their own computers rather than a terminal to a mainframe. Sometimes, the term refers to using computers at home for work and/or entertainment in contrast to business use only.

The current standard has a data transfer rate of up to 400Mbps, with the possibility for further increases in the future. For optimum benefit to consumers, the IEEE 1394 standard has such features as isochronous Time dependent. Real time voice, video and telemetry are examples of isochronous data. (communications) isochronous - /i:-sok'rn-*s/ A form of multiplexing that guarantees to provide a certain minimum data rate, as required for time-dependent data such as video or audio. data transfer, "Plug and Play" for immediate connection and function, and "Hot Plug In" to add or remove devices even when the power is on and without the need to restart the host. In addition, the IEEE 1394 serial bus does not require a computer when used for digital AV equipment. "Sony chose Apple's FireWire implementation of IEEE 1394 as the basis for this new family of LSIs because of such merits as a high-speed transfer rate, real time data processing data processing or information processing, operations (e.g., handling, merging, sorting, and computing) performed upon data in accordance with strictly defined procedures, such as recording and summarizing the financial transactions of a , simple connections and low cost," commented Jean Pierre Lassaude, vice president semiconductor marketing, Sony Semiconductor Company of America. "The IEEE 1394 standard makes it practical to put a digital interface on consumer products. Products from Sony and Apple using this standard will help people communicate the beauty of nature and the art of man with the integrity of the senses only possible through digital recording," said Jonathan Zar, Senior Business Development Manager, Apple Computer. In addition to the FireWire implementation of IEEE 1394, both LSIs that Sony is introducing Wednesday have circuitry to support AV-Protocol, making it easy to connect to digital VCRs as well as future digital AV products that have the IEEE 1394. The LSIs will be sold to outside companies and be incorporated into Sony-brand computer input digital cameras, digital video camcorders and multimedia peripheral equipment. The LSIs will be displayed at Comdex 95, to be held in Las Vegas on Nov. 13, 1995. -0-
